This is a video from the Hercules ROV (remotely operated underwater vehicle) being guided by a research team aboard the the E/V (exploration vehicle) Nautilus off the coast of Mexico filming a deep sea Halitrephes maasi jellyfish that looks like an honest-to-God firework explosion. WIthout any light though it would actually be almost entirely transparent, it just looks like a firework thanks to the reflection of the rover's lights off the creature's radial canals and tentacles. Crazy, right? You know, Mother Nature, as much shit as I talk, sometimes you really are alright. "Anal spiders." Um, what? "Nothing, nothing -- just brainstorming." YOU FILTHY BILGE HAG.
Keep going for the video.
Thanks to Lucinda, who agrees in the case of almost everything, under the sea creatures did it first.
